摘要： PURPOSE:To enhance the safety to the human body and to preserve a red corpuscle for a long period by constituting a blood collecting bag of a resin in which a plasticizer is scarcely eluted to the contents, and in cluding a hemolysis suppressing substance in a constitution material of a red corpuscle bag or in the red corpuscle bag. CONSTITUTION:A blood collecting bag 1 is formed like a bag by superposing a sheet material made of a resin, and welding it by heating in a seal part 2. It is constituted of a resin material in which an elution of a plasticizer to the contents (blood, anticoagulant) is scarcely generated. A red corpuscle bag 40 is an exclusive bag for containing and preserving a red corpuscle, and formed like bag by superposing a sheet material made of a resin, and welding it by heating in a seal part 41. As for the red corpuscle bag 40, it is desirable to constitute it of polyvinyl chloride containing di(ethylhexyl) phthalate(DEHP) being a hemolysis suppressing substance as a plasticizer, and by using DEHP as a plasticizer, the DEHP eluted in the red corpuscle bag 40 generates a protective action of a red corpuscle membrane, hemolysis is suppressed, and it contributes to preserving a red corpuscle for a long period.
